Electrical connector

Abstract

An electrical connector includes an insulating body, a terminal set, a wire, and a shielding housing having an upper shell body and a lower shell body. A support part of the first buckling sheet which is penetrated through a first buckle hole of the lower shell body is rivetedly pressed on an outer peripheral edge of the first buckle hole of the lower shell body. An upper side and a lower side of the wire are pressed by a top plate of the upper shell body and the bottom plate of the lower shell body so that the upper and lower shell bodies of the shielding housing can be integrally formed, thereby promoting the bulk intensity of the produced electrical connector, preventing the internal mechanism of the electrical connector from damage due to the oscillation of the wire, and promoting the reliability of the produced electrical connector.

What is claimed is: 
     
       1. An electrical connector, comprising an insulating body, a terminal set insertedly mounted in the insulating body, a wire connected to a rear end of the terminal set, and a shielding housing comprising an upper shell body and a lower shell body that are vertically corresponded, in which the lower shell body comprises a front shell that is integrally extended from a front end thereof to cover outside the insulating body to form a connection plug, and the upper and lower shell body of the shielding housing are mutually fastened to form a wired chamber so that to wrap a wired position of the terminal set and the wire, characterized in that two side flanges of a rear end of a bottom plate of the lower shell body are opened with first buckle holes, bottoms of a left-rear side plate and a right-rear side plate of the upper shell body are protrudingly formed with first buckling sheets, the first buckling sheets comprises folded parts and support parts penetrated through the first buckle holes of the lower shell body, in which, when bending the folded parts of the first buckling sheets, the support parts of the first buckling sheets are rivetedly pressed on an outer peripheral edge of the first buckle holes of the lower shell body, left and right sides of the wire are clamped by a left-rear side of a clamping part and a right-rear side of the clamping part of the upper shell body, and upper and lower sides of the wire are pressed by a top plate of the upper shell body and the bottom plate of the lower shell body, wherein a middle front side of the top plate of the upper shell body is configured with a second buckle hole, a middle support arm is extended from a front edge of the top plate of the upper shell body, a middle second buckling sheet extended upward from a rear edge of a top surface of the front shell of the lower shell body is engaged in the second buckle hole of the upper shell body, and the middle second buckling sheet is folded to reversely buckle and press a peripheral edge of the second buckle hole of the upper shell body so that the middle support arm of the upper shell body and the top surface of the front shell of the lower shell body are mutually abutted. 
     
     
       2. The electrical connector as claimed in  claim 1  characterized in that the upper shell body comprises the top plate, a first left side plate and a first right side plate which are extended downward from two sides of the top plate, and third buckling sheets protrudingly arranged on bottoms of the first left side plate and the first right side plate, and the lower shell body comprises the bottom plate, a second left side plate and a second right side plate which are extended upward from two sides of the bottom plate, the second left side plate and the second right side plate of the lower shell body are outwardly clamped by the first left side plate and the first right side plate of the upper shell body, and the third buckling sheets of the upper shell body are folded on bottom edges of the second left side plate and the second right side plate of the lower shell body to reversely buckle the bottom plate of the lower shell body. 
     
     
       3. The electrical connector as claimed in  claim 2  characterized in that the first left side plate and the first right side plate of the upper shell body are configured with a plurality of engaging holes, the second left side plate and the second right side plate of the lower shell body are configured with a plurality of convex points which are engaged in the corresponding engaging holes of the upper shell body. 
     
     
       4. The electrical connector as claimed in  claim 2  characterized in that both sides of a front end of the top plate of the upper shell body is concaved downward with two concave points which are respectively distanced from the first left side plate and the first right side plate with clearances, and front sides of top edges of the second left side plate and the second right side plate of the lower shell body are configured with guide elastic pieces which are slidably embedded in the clearances of the upper shell body. 
     
     
       5. The electrical connector as claimed in  claim 1  characterized in that the insulating body comprises a base seat and a tongue piece which are integrally formed, a rear end of the base seat is installed with a wire clip, the length of the tongue piece is not greater than 11 millimeters, the sum of the lengths of the base seat and the tongue piece is not greater than 14 millimeters, the sum of the lengths of the base seat, the tongue piece and the wire clip is not greater than 16 millimeters, and the width of the wire clip. 
     
     
       6. The electrical connector as claimed in  claim 5  characterized in that the width of the upper shell body/the lower shell body is not greater than 15.5 millimeters, the length measured from a front edge of the front shell of the lower shell body to the upper shell body/a rear edge of the bottom plate of the lower shell body is not greater than 23.9 millimeters, and the entire length measured from a frontmost edge of the front shell of the lower shell body to the upper shell body/a rearmost end of the lower shell body is not greater than 28.9 millimeters.
